DOVERPHOS 6
Triisodecyl Phosphite
Doverphos 6 is triisodecyl phosphite (TDP). It is an alkyl phosphite with low molecular weight and
high phosphorus content. Doverphos 6 is an effective liquid phosphite heat stabilizer for
polyolefins, polyurethanes, coatings, ABS, lubricants, and polyethylene terephthalate. Typical use
levels range from 0.05 to 3.00% for most applications. Doverphos 6 can be used in rigid and
plasticized PVC applications to give brighter, more consistent colors and improve early color and
clarity in unpigmented compounds. Use levels in PVC range from 0.25 to 1.00%.
